Abstract
Reinforced polyurethane product is mainly used as substitute of some metal parts in automobile. It contains glass fiber in 25-30 wt% of product and polyurethane composite including polyether in 25-35 wt% of product and isocyanate in 35-45 wt% of product. The technological process includes heating mould, spreading glass fiber, depositing, foaming, setting, demoulding and other steps. The product is light, strong, fireproof and easy to produce.
Description
The present invention relates to a kind of polyurethane products and production technique thereof, its finished product mainly are used as the substitute of some metal insert in the automobile manufacture industry.
Car door assembly, gusset interior trim assembly, luggage-boot lid assembly matrix, the dashboard matrix of producing in the automobile manufacture industry mostly adopts metal products at present, based on iron sheet.But the metal products complex manufacturing, difficulty of processing is big, cost of investment is high, and does not meet automobile lightweight, software requirement.The part vehicle has adopted wood fibre, paper pulp and plastic material at present.Wood fibre, paper oar are all sticking molded by resinous material, and production energy consumption is big, and product poor processability, intensity are low, and exhaust gas discharged, waste water environmental pollution are serious.Plastic material complete processing complexity, mould and equipment drop into huge, and finished product heat resistanceheat resistant poor performance, and work-ing life is short.
For solving the various shortcomings that exist in the prior art, the object of the present invention is to provide a kind of every performance index to meet the automobile production requirement, and production technique strengthen polyurethane products simply and easily, and the production product technology of this product.
Described enhancing polyurethane products comprise glass fibre and polyurethane combined material, it is characterized in that containing the glass fibre of finished product gross weight 25-30%, contain the polyethers of finished product gross weight 25-35% and the isocyanic ester of 35-45% in the polyurethane combined material.
The production technique of above-mentioned enhancing polyurethane products requires to carry out molding processing according to shape of product, it is characterized in that comprising following processing step:
A. utilize die heater that mould is heated, make die temperature keep 40-80 ℃.
B. glass fibre is spread mould, and the controlling fiber amount is the 25-30% of finished product gross weight.
C. polyurethane combined material is injected die cavity with foaming machine, contain the polyethers of finished product gross weight 25-35% and the isocyanic ester of 35-45% in the polyurethane combined material.It is infiltrated in the glass fibre foam voluntarily, solidify, the demoulding is taken out after the moulding.
This strengthens polyurethane products, and every performance index meet the automobile production requirement, has light specific gravity, intensity is big, and advantage such as fire-retardant, easy processing can substitute original metal products, wooden, paper pulp and plastics.And this product processes is simple and convenient, cost of investment is low, and is with short production cycle, and production process does not have the three wastes substantially and produces, and solved wooden in the past, paper pulp and plastics cause severe contamination to environment problem preferably.
Below the invention will be further described with embodiment.
Described enhancing polyurethane material is selected length 50-70mm for use, and diameter is 0.4-0.6mm, glass fibre as reinforcing fiber materials.
Comprise the flame retarding polyether of finished product gross weight 28-32% and the isocyanic ester of 38-42% in the polyurethane combined material.
With above-mentioned component dosage and comprise that following processing step produces: mould heats-and glass fibre shop mould-polyurethane combined material injection molding-foaming voluntarily, curing and demolding take out.Die temperature preferably is controlled at 55-65 ℃, sprays releasing agent in advance before the mould of glass fibre shop in die cavity, is convenient to the demoulding and increases product surface smooth finish.Goods promptly can be used for the installation production of next procedure after deburring, surface finish are handled.
